[0002] A casting mold is a precision tool specifically used to manufacture metal parts. Its core function is to shape the shape and internal structure of the molten metal during its cooling and solidification process. This mold not only determines the geometry of the final casting, but also affects its mechanical properties and surface quality. Gravity casting is a widely used method in metal casting technology. It relies on the gravity of the molten metal itself to allow it to flow naturally into the mold for molding without applying any additional pressure. The gravity casting process is known for its simplicity and economy. It is suitable for a variety of casting materials and castings of varying complexity. In this method, the molten metal passes through the gate and runner system and gradually fills the mold cavity by gravity.

[0016] A processing method for producing a fastener comprises the following steps:

[0017] S1. First, the cleaning piece is set on the top of the filter element, and the filter element is fixedly installed in the feed pipe through the fixing groove, and then the feed pipe is fixedly installed in the fixing piece, and the fixing piece is installed on the top of the mold body, so that the feed port of the mold body and the discharge port of the feed pipe are aligned, and then the installation sleeve is installed on the outside of the fixing piece, and the reinforcement piece is installed on the installation sleeve, so that the reinforcement piece is fixed to the fixing piece, and the installation is completed;

[0018] S2. Then, pour the molten metal into the feed pipe from top to bottom, so that the molten metal flows into the cavity in the mold body through the feed pipe. When the molten metal flows in the feed pipe, it first passes through the cleaning member, drives the turbine fan, thereby driving the cleaning rod to rotate on the surface of the cone, and then passes through the filter holes on the cone to filter the impurities in the molten metal, and then enters the cavity in the mold body through the outlet of the feed pipe;

[0019] S3. Finally, after the impurities in the molten metal are filtered out, they remain on the surface of the cone. As the cleaning rod rotates on the surface of the cone, the impurities are pushed into the circulation channel along the surface of the cone. As the impurities and part of the molten metal in the circulation channel increase, they move upward along the circulation channel and are discharged from the outlet of the circulation channel. The discharged impurities and part of the molten metal are mixed with the newly entered molten metal through the rotating turbine fan and flow downward again to avoid clogging of the filter holes by impurities. The impurities and part of the molten metal in the circulation channel are mixed with the newly entered molten metal.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention ensures that impurities can be removed efficiently during the flow of the molten metal by cooperating with the filter element, while avoiding the accumulation of impurities and the blockage of the pipeline caused by the solidification of the molten metal. The cone and the filter hole in the filter element enable the molten metal to flow along the conical surface, and the impurities are effectively trapped. The C-shaped design of the circulating flow channel allows the filtered impurities and part of the molten metal to re-enter the feed pipe to keep the flow channel unobstructed. This design not only prevents the accumulation of impurities, but also avoids the solidification of the molten metal through the circulating flow, thereby ensuring the continuity and stability of production;

[0022] 2. The present invention improves the efficiency and cleaning ability of the system through the cleaning element. The rotating turbine fan and the cleaning rod automatically work when the metal melt flows, scrape off the residual impurities on the surface of the filter element, and push them into the circulation channel, thereby realizing the automatic cleaning function. This automatic cleaning mechanism reduces the need for manual maintenance and ensures the continuous and efficient operation of the filter element. At the same time, the rotation of the turbine fan breaks up the flowing metal melt, promotes its uniform mixing, avoids local solidification, and improves the quality and consistency of the product. The cooperation between the baffle and the feed hole enables a small part of the metal melt and impurities to enter the circulation channel through the feed hole, further optimizing the flow path and mixing effect of the metal melt.

[0023] 3. The combined design of the fixings, mounting sleeves, reinforcements and feed pipes in the present invention not only simplifies the disassembly and assembly process and enhances the structural stability of the equipment, but the modular structure makes the replacement and maintenance of individual components simple and quick, reducing downtime and maintenance costs. Operators can quickly replace damaged or aged components without disassembling the entire system, thereby improving the continuity and stability of the production line.

In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "set" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be the internal connection of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0038] Reference Figures 1 to 6 In an embodiment of the present invention, a processing mold for fastener production and a processing method thereof include: a mold body 1, a fixing member 2 is fixedly arranged on the mold body 1, and the fixing member 2 is provided with two groups symmetrically distributed on the mold body 1, a mounting sleeve 3 is sleeved on the outer side of the fixing member 2, and a reinforcing member 4 is provided on the mounting sleeve 3 to abut and fix the fixing member 2, and the two groups of fixing members 2 are closely fitted by the reinforcing member 4, a feed pipe 5 is clamped in the fixing member 2, and four groups of feed pipes 5 are arranged and evenly distributed in the fixing member 2, and the four groups of feed pipes 5 form a complete pipeline, and a filter 6 for filtering the metal melt and removing impurities therein is inserted in the feed pipe 5, and a cleaning member 7 is rotatably arranged on the filter 6, which is driven to rotate with the flow of the metal melt to scrape off the residue on the surface of the filter 6;

[0039] The filter element 6 includes a fixing ring 61 clamped with the inside of the feed pipe 5, a cone 62 is fixedly arranged on the fixing ring 61, and the cone 62 is conical so that the molten metal flows along the conical surface. The cone 62 is provided with filtering holes 63, and the filtering holes 63 are arranged in a plurality of groups evenly distributed on the cone 62. The top of the cone 62 is fixedly connected with an insertion rod 64;

[0040] The side end of the feed pipe 5 is connected with a circulation channel 52, the cross section of the circulation channel 52 is C-shaped, the feed port of the circulation channel 52 is arranged at the side end of the cone 62, and the flow channel at this connection is inclined upward, so that the metal melt can flow into the circulation channel 52, and the discharge port is arranged above the cleaning member 7, and the flow channel at this connection is inclined downward, so that the metal melt can flow out of the circulation channel 52;

[0041] Among them, the metal melt enters the feed pipe 5 under the action of gravity and passes through the filter 6. The blocked impurities and metal melt flow into the circulation channel 52, and under the accumulation effect of their continuous inflow, they flow out from the outlet of the circulation channel 52 and re-enter the feed pipe 5, preventing the accumulation of impurities and preventing the metal melt from solidifying and causing blockage.

[0042] For this explanation, in the present technical solution, the molten metal poured into the mold body 1 is generally left to stand before pouring to allow impurities to separate naturally according to density, so that impurities with higher or lower density sink to the bottom of the melt or float on the surface of the melt, thereby removing the impurities. However, there will still be impurities with density similar to that of the molten metal that cannot be completely removed. These impurities will flow with the melt during the pouring process, and because these impurities have a similar density to that of the molten metal, they are easily carried and moved with the flow of the melt during the flow of the melt, thereby moving upward with the molten metal in the circulation channel 52.

[0043] Reference Figures 4 to 5A reinforcing rod 53 is fixedly connected to the discharge through-connection port of the feed pipe 5 and the circulation channel 52 to strengthen the support between the circulation channel 52 and the feed pipe 5. A baffle 57 is fixedly connected to the feed through-connection port of the feed pipe 5 and the circulation channel 52. A feed hole 58 is formed through the baffle 57. There are multiple groups of feed holes 58, which are evenly formed on the baffle 57. The aperture of the feed hole 58 is larger than the filter hole 63 to allow impurities to pass through. A fixing groove 54 is formed on the inside of the feed pipe 5. A fixing ring 61 is plugged into the fixing groove 54. A connecting card groove 55 is formed on one side of the feed pipe 5. A connecting card block 56 is fixedly connected to the other side of the feed pipe 5. Connecting card grooves 55 and connecting card blocks 56 are also formed on both sides of the circulation channel 52. The connecting slot 55 is connected to the connecting slot 55 on one side of the feed pipe 5, and the connecting block 56 fixedly connected on the other side of the circulation channel 52 is fixedly connected to the connecting block 56 fixedly connected on the other side of the feed pipe 5. The four groups of feed pipes 5 can be quickly assembled through the connecting slots 55 and the connecting blocks 56 to form a complete pipeline. The flowing molten metal can be blocked by the baffle 57 to prevent a large amount of molten metal from entering the circulation channel 52, and with the cooperation of the cleaning member 7, a small part of the molten metal and the filtered impurities enter the circulation channel 52 through the feed hole 58, and as the molten metal and the filtered impurities in the circulation channel 52 increase, they are discharged from the discharge port of the circulation channel 52 and enter the feed pipe 5 again.

[0044] The above scheme is adopted: by connecting the connecting slots 55 and the connecting blocks 56 to each other, multiple groups of feed pipes 5 form a complete pipeline system, which not only simplifies the assembly process of the feed pipes 5, but also enhances the stability of its structure, ensuring that it will not loosen or leak in a high temperature and high pressure environment. Through the structural design of the connecting slots 55 and the connecting blocks 56, the tight connection between the feed pipe 5 and the fixing part 2 and the circulation channel 52 is ensured, thereby enhancing the stability and sealing of the entire system.

[0045] Reference Figures 7 and 8The cleaning member 7 includes a connecting sleeve 71 sleeved on the outside of the plug rod 64, and the connecting sleeve 71 is rotatably connected to the plug rod 64. A turbine fan 72 is fixedly connected to the top of the connecting sleeve 71. The water level blades of the turbine fan 72 are set at a certain angle so that when the molten metal passes through, the turbine fan 72 is pushed to rotate. A cleaning rod 73 is fixedly connected to the bottom end of the connecting sleeve 71. The cleaning rod 73 is in contact with the surface of the cone cylinder 62. There are multiple groups of cleaning rods 73, which are evenly distributed at the bottom end of the connecting sleeve 71. The cleaning rod 73 is L-shaped, wherein the long rod of the L-shape is arc-shaped and in contact with the surface of the cone cylinder 62, and the short rod of the L-shape is The inner wall of the baffle 57 is fitted, and when the molten metal passes through the turbine fan 72, it pushes the turbine fan 72 to rotate, thereby driving the cleaning rod 73 to rotate, and scraping off the impurities sticking to the surface of the cone 62. Since the long rod of the L-shaped cleaning rod 73 is an arc surface, it will push the impurities to move toward the baffle 57 during the rotation process, and push the impurities into the feed hole 58 under the action of the L-shaped short rod. During the rotation of the turbine fan 72, it will contact the molten metal flowing in the circulation channel 52, break it up, and mix it with the new molten metal poured in, so as to prevent the molten metal in the circulation channel 52 from solidifying due to temperature loss.

[0046] The above scheme is adopted: by arranging the turbine fan 72 and the cleaning rod 73 in the filter element 6, the impurities attached to the surface of the flowing molten metal can be effectively scraped off, the turbine fan 72 rotates when the molten metal flows, so that the cleaning rod 73 rotates accordingly, thereby cleaning the impurities on the surface of the cone 62, and the turbine fan 72 of the cleaning element 7 can break up the flowing molten metal by contacting with the molten metal, so that it is fully mixed with the newly added molten metal. This action can not only reduce the local solidification phenomenon, but also make the molten metal have better fluidity, ensuring a uniform filling effect in the mold.

[0047] Reference Fig. 9 The fixing part 2 includes a connecting plate 21 fixedly connected to the top of the mold body 1, a clamping tube 23 fixedly connected to the connecting plate 21, and a thermal insulation material is arranged inside the clamping tube 23 to prevent the rapid loss of the temperature of the metal melt. The outer side of the top of the clamping tube 23 has an inverted arc corner, and a cavity 24 is opened in the clamping tube 23. The cavity 24 is adapted to the feed pipe 5. A fixing rod 22 is fixedly connected to the connecting plate 21. There are multiple groups of fixing rods 22, which are evenly distributed on the outside of the clamping tube 23. The feed pipe 5 can be quickly installed and positioned through the fixing part 2, so that the discharge port of the feed pipe 5 is aligned with the feed port of the mold body 1.

[0048] The above scheme is adopted: the feed pipe 5 can be firmly fixed on the mold body 1 through the connecting plate 21 and the fixing rod 22 in the fixing part 2, ensuring that the feed pipe 5 is aligned with the feed port of the mold body 1, and ensuring that the metal melt will not leak or flow poorly due to the displacement or misalignment of the feed pipe 5 during the flow process, thereby ensuring the stability and accuracy of production. The clamping cylinder 23 in the fixing part 2 is filled with thermal insulation material, which can effectively reduce the temperature loss of the metal melt, help maintain the fluidity of the metal melt, and prevent it from solidifying due to temperature drop before entering the mold, thereby avoiding the risk of pipeline blockage and improving production efficiency.

[0049] Reference Figure 10 to Figure 11 The mounting sleeve 3 includes a mounting sleeve 31 sleeved on the outside of the clamping sleeve 23, a fixing hole 32 is formed through the top of the mounting sleeve 31, and a plurality of fixing holes 32 are arranged and evenly distributed on the top of the mounting sleeve 31, each group of fixing rods 22 is slidably plugged with a group of fixing holes 32, a mounting groove 33 is formed on the top of the mounting sleeve 3, the mounting groove 33 is L-shaped, and a plurality of mounting grooves 33 are arranged and evenly distributed on the top of the mounting sleeve 3, a sliding groove 34 is formed on the inner side of each group of mounting grooves 33, and the mounting grooves 33 are connected to the sliding grooves 34, and the reinforcing member 4 includes a mounting groove 33 The plug-in mounting plate 41 has a slide plate 42 fixedly connected to the side end of the mounting plate 41. The slide plate 42 is slidably connected to the sliding groove 34, and the mounting plate 41 can be restricted in the mounting groove 33 through the slide plate 42 and the sliding groove 34. A connecting rod 43 is fixedly connected to the inner side of the mounting plate 41. The connecting rod 43 consists of a group of straight rods and a group of semicircular fixed cylinders. Balls 44 are embedded in the semicircular fixed cylinders, and the balls 44 are rotatably connected to the connecting rod 43. The balls 44 abut against the outer side of the clamping cylinder 23. There are multiple groups of connecting rods 43, which are evenly distributed on the inner side of the mounting plate 41.

[0050] The above scheme is adopted: by inserting the mounting plate 41 into the mounting groove 33, during the installation process, the connecting rod 43 on the inner side of the mounting plate 41 abuts against the clamping tube 23 through the ball 44, thereby reinforcing the fixing part 2 and the feed pipe 5, effectively increasing the supporting area of ​​the feed pipe 5, ensuring its stability and position fixation, and avoiding displacement or loosening due to uneven force during the production process.

[0051] The working principle of the present invention is as follows: when in use, the filter element 6 is first connected to the cleaning element 7 through the insertion rod 64 and the connecting sleeve 71, and the fixing ring 61 in the filter element 6 is inserted into the fixing groove 54 on one group of the feed pipes 5, and then the remaining three groups of the feed pipes 5 are connected in sequence through the connecting card groove 55 and the connecting card block 56, so that the four groups of feed pipes 5 form a complete pipeline, and the filter element 6 and the cleaning element 7 are wrapped therein to fix the filter element 6, and then one group of fixing elements 2 is connected to the mold body 1 through the connecting plate 21, and then the complete feed pipe 5 is placed in the cavity 24 in this group of fixing elements 2, and the discharge port of the feed pipe 5 is aligned with the feed port of the mold body 1, and then the other group of fixing elements 2 is connected to the mold body 1 through the connecting plate 21. The connecting plate 21 of the fixing part 2 is connected to the mold body 1, so that the cavities 24 in the two groups of fixing parts 2 wrap and fix the feed pipe 5, and then the fixing rod 22 in the fixing part 2 is inserted into the fixing hole 32 in the mounting sleeve 3, so that the mounting sleeve 3 is installed on the outside of the clamping tube 23, and then the mounting plate 41 is inserted into the mounting groove 33 through the slide plate 42 and the sliding groove 34. During the insertion process, the ball 44 on the connecting rod 43 on the inner side of the mounting plate 41 abuts against the clamping tube 23, and slides downward under the action of the arc angle on the outer side of the top of the clamping tube 23, so that multiple groups of ball 44 abut against the side end of the clamping tube 23, and the spliced ​​and assembled fixing part 2 and the feed pipe 5 are reinforced to complete the installation, and then the metal melt is The molten metal poured into the feed pipe 5 and flowing into the feed pipe 5 first passes through the turbine fan 72, contacts the blades of the turbine fan 72 while passing through, and drives the turbine fan 72 to rotate. When the turbine fan 72 rotates, it drives the cleaning rod 73 to rotate. Then, the molten metal continues to move downward until it contacts the cone cylinder 62 and passes through the filter hole 63 on the cone cylinder 62, so that impurities in the molten metal remain on the cone cylinder 62, and the molten metal that passes through enters the cavity in the mold body 1. As the molten metal continues to flow in, the turbine fan 72 is driven to rotate continuously, so that the cleaning rod 73 rotates accordingly, pushing the impurities on the cone cylinder 62 to move toward the baffle 57 along the opposite direction of the arc-shaped long rod of the L-shaped cleaning rod 73 until it is moved to the side of the baffle 57 At this time, since the short rod of the L-shaped cleaning rod 73 that is in contact with the inner wall of the baffle 57 is rotating, it will push the impurities to move along the inner wall of the baffle 57 until the impurities are moved to the feed hole 58 and pushed into the circulation channel 52 through the feed hole 58. As the impurities and molten metal in the circulation channel 52 increase, the molten metal will move upward in the circulation channel 52 and drive the impurities to move upward until it flows out from the discharge port of the circulation channel 52 and re-enters the feed pipe 5. Since the discharge port of the circulation channel 52 is higher than the cleaning member 7, the molten metal flowing out of the circulation channel 52 will contact the rotating turbine fan 72 to break up the molten metal flowing out of the circulation channel 52 and the impurities therein, and mix them with the newly flowing molten metal.The cooperation between the circulation channel 52 and the filter element 6 ensures that impurities can be efficiently removed from the molten metal during its flow, while avoiding the accumulation of impurities and the blockage of the pipeline caused by the solidification of the molten metal. The cone 62 and the filter hole 63 in the filter element 6 enable the molten metal to flow along the conical surface, and the impurities are effectively retained. The C-shaped design of the circulation channel 52 allows the filtered impurities and part of the molten metal to re-enter the feed pipe 5 to keep the flow channel unobstructed. This design not only prevents the accumulation of impurities, but also avoids the solidification of the molten metal through the circulation flow, thereby ensuring the continuity and stability of production. The efficiency and cleaning ability of the system are improved by the cleaning element 7. The rotating turbine fan 72 and the cleaning rod 73 automatically work when the molten metal flows, scrape off the residual impurities on the surface of the filter element 6, and push them into the circulation channel 52, thereby realizing the automatic cleaning function. This automatic cleaning The mechanism reduces the need for manual maintenance and ensures the continuous and efficient operation of the filter element 6. At the same time, the rotation of the turbofan 72 breaks up the molten metal flowing through, promotes its uniform mixing, avoids local solidification, and improves the quality and consistency of the product. The cooperation between the baffle 57 and the feed hole 58 allows a small part of the molten metal and impurities to enter the circulation channel 52 through the feed hole 58, further optimizing the flow path and mixing effect of the molten metal. The combined design of the fixing member 2, the mounting sleeve 3, the reinforcement member 4 and the feed pipe 5 not only simplifies the disassembly and assembly process, but also enhances the structural stability of the equipment. The modular structure makes the replacement and maintenance of individual components simple and fast, reduces downtime and maintenance costs, and operators can quickly replace damaged or aged components without disassembling the entire system, thereby improving the continuity and stability of the production line. ;
